Re: Hatch handle seat (corners) for Goiot tradition series

Germain Jean-Pierre

Hello Mike,

I am surprised the corner seats are failing. Eleuthera is the same vintage and corners are still in good order. 

However, from my experience, I’ve replaced some of the handles... probably due to UV damage over the years. Expect a crazy price.

Hi Charles,

Thanks for laying out the process for me. Very cool. And I appreciate your thoroughness.

I think it's best if we get you a sample in hand. If we can't find one from another owner, perhaps I can remove one off my boat and ship it.

Does anyone reading this have a spare Goiot hatch corner seat (tradition series) that we could borrow for this project?

If there's not a big price difference between materials then the aluminum might be better. My existing ones are a type of polymer and most have not survived the test of time. That said, I'm not sure how long they've been installed (decades?) so perhaps replacement now is totally acceptable. I also don't want all of my handles to now fail if the corner seats are stronger (see attached photo).

At any rate, I'll work to get you a proper sample asap and we can go from there.

Hello Mike,

Thank you for the kind words on the parts I made. Yes, I am in the US.

It took me 5 or 6 weeks to make the batch of parts you see in the pictures. The steps are:

  • I spent about a week measuring and drawing the parts, thinking about which measurements are critical for the part to work, and then tweaking the 3D model and cut path. On this project, I am wondering a lot about
    • The inside corner where the plate and wall meet. I am thinking about doing a rounded curve with a ball mill and need to make sure it will not interfere with the latch sweep.
    • The necessary thickness of the base plate and if we might need to make it from aluminum to survive abuse (or if the touch composite I used on the handles will do the job well)
  • After tweaking the design files, I cut samples from scrap, verified the fit on the boat, and then ordered material.
    • The black plastic you see takes me about a week to get in
    • The aluminum can sometimes be *found* in the cut-offs pile of my shop. Otherwise, it is usually 2 days to get in the stock.
  • Then I waited to get machine time to cut the parts. The machines in the shop usually run 24x7 and personal projects have to run on the weekends.
  • Once I had machine time, things happened really fast. Most of the parts you saw in my pictures were a minute or two per cycle.
  • Then the aluminum parts were anodized, about a 3 day turn around.
Assuming no surprises, this is about 4 to 6 weeks.

Without a sample of the original part in hand, there is a really high probability of surprises. 

Maybe we can find somebody in the group who has a broken one they could part with temporarily? 

Let's find a way to do this, I enjoy these sorts of challenges.
